I am totally curious if anyone has picked up where this guy was going? Has anyboby tried supplying the OMP with something other than crankcase oil? Seems to me, a block-off plate, with an external tap that could be sent to an external oil reserviour (like his old bike) could be a desirable option.

It's been done. It's in the FAQ.

Yeah, I found a thread that had a link for these adapters. They work with the existing metering pump.

I like the external reservoir idea. Its just as easy to do that as it is to add premix every time you fill up. Plus it seems odd to have your crankcase oil sucked out by "design", but rotaries are not conventional. After reading several threads about premixing, I'm still undecided as there are many varied opinions and many valid points. Sounds like the best way is to go 50/50...premix/mop. Same as with standard oil and 2 cycle oil. Many ways to look at it. After saying all that, my future intentions are to get one of those adapters, use an ext. reservoir and pre-mix in small amounts. Maybe there is a way to reduce the oil flow on the MOP so you dont use too much oil.

Sorry im new but figured id ask this in here.

Do i put the oil actully in the gas tank or do i just pour it into the oil place? I havnt added oil to it since i got the car i thought that it would do it on its own. I did get a new oilchange like 2 days afterwards.

You mix the premix oil with your gas.

Put it in first, then add your fuel 'on top of it', to kind of mix it around.

CrypticApathy

what if i just filled up should i put it in still?

Just so i dont screw anything up i DO put it in the gas tank?

BTW im not talkinga bout premix im talking about oil.

Is premix a must?

With premixing, you add the oil to the tank at fillup. The crankcase oil which is used by default, of course goes in the standard oil fill tube. As I've learned the past couple days, these rotaries need oil on the apex seals. On the RX7's and mazda aircraft engines and whatever else they are used in, the oil is injected or dribbled by the metering oil pump (MOP). This oil is pulled from the crankcase, supposedly using about a quart in 1000 miles. According to some, mazda engineers felt it wouldnt do for the general public to have to check/add to a separate reservoir or pre-mix their fuel. Well, to me its just as counter-intuitive to have to check your crankcase oil that frequently. A good piston engine well maintained that doesnt leak, should need very little or no oil in 3000 miles. Alot of people prefer premixing cause they feel things get lubed better plus you can use 2 stroke oil in the gas, rather than regular old crankcase oil. 2 cycle oil burns better and doesnt leave as much buildup. If you do your homework, you'll find many different opinions on premixing versus injecting and the lubrication benefits of 2 cycle oil versus motor oil. Another mod option is to use an external reservoir and run an oil of your choice. That way your crankcase oil isnt depleted and your fuel injectors dont get gummed up from the oil flowing through them via premix. Many ways to look at it. Definitely do the reading and make up your own mind.

ok so i DONT need to go out and get oil to pour in the gas tank? The oil thats in the oil part is fine i dont need to add anything else? I dont want my seals to dry out or break or anything.

wes_c

Im really a newbie too, so ....my advice would be to do some searching in the archives and faq's and understand it all a little more first, then make up your own mind.

CrypticApathy

let me rephrase this. Does the engine automatically add oil from the oil area of the car to lubricate.

Yes or No?

Valkyrie

No...the Oil Metering Pump does that... So you don't need to do anything... but you can.

Unless your OMP is broken, then you'd need to add oil, or kiss your engine goodbye.

wes_c

Yes, if the factory system is working properly it will pull oil from your crankcase and burn it. You will need to check it regularly because it will deplete your oil over time.

CrypticApathy

ok thank you. All i wanted to know is that im not screwing up my engine by not adding oil. I thought the engine did it own its on which it does. But ive also driven 2 strokes where you had to add oil to the engine or it wouldnt last long at all. I just dont want my new (relativly speaking) car breaking down b/c of something stupid i did instead of rutine maintence.

Yeah, don't worry about it. If your OMP is working properly (it probably is), then everything is taken care of...

Just don't neglect to check your oil often. I made the mistake of running my motor out of oil on my first FC (I was 17 at the time) and the engine seized on me (lol). I took apart that block several months ago, and WOW, you couldn't even SEE the side-seals in the rotors. They had melded into their slots!

Moral of the story, rotaries need oil...
